森林降水化学研究综述

Review on the Study of Forest Precipitation Chemistry

森林降水化学是研究大气降水的化学物质输入及其对森林生态系统生物物质循环影响规律的一门分支学科。该文综述了有关森林降水化学研究的几个方面。其中包括森林降水化学的范畴，有关的水文学与生态学概念及其发展；世界范围内森林降水化学物质输入规律；森林降水化学的动态变化规律及其影响因子。最后提出了降水化学研究中应注意的几个问题。

Forest precipitation chemistry is a newly-developed branch subject of ecology and foresthydrology concerned with the research of input of chemical substances by atmospheric precipitationand its effects on the biological cycling of minerals in forest ecosystem.In this paper,some aspectsabout forest precipitation chemistry study are reviewed,including research scope,related Concepts andevolution;changes of inputs of chemical substances by precipitation in different forests in the world;spatial and temporal dynamics of precipitation chemistry and factors affecting it.Some questions areraised for attention and further research in the future study.
